Spieth loses his cool

Jordan Spieth was left none too pleased after his approach shot at the par-4 17th ended up in the bunker.

Spieth was one of the early starters at Oakmont on Thursday, and while that brought gentler conditions due to the rain that fell overnight, it also provided its fair share of frustration.

Returning after the first of several rain delays throughout the day, Spieth headed to the 17th hoping for a birdie at one of the more forgiving holes on the course.

The defending champion’s wedge approach shot looked to have been judged to perfection, but the combination of back spin and Oakmont’s extremely quick and unforgiving greens saw the ball end up in a greenside bunker.

Adding to Spieth’s frustration was that his group had been warned for slow play moments earlier, a growing problem for the 22-year-old – as his his increasing testiness on the course, which is liable to start getting him in trouble sooner rather than later, as fans on Twitter started pointing out:

Spieth is veering into that territory where folks are going to call him a whiner.
